Well, mines not the case here...I have the same problem and I don't share with any other computer...the only network I have is with my ISP because I have a wireless connection...other than that, no other computer can access my computer. Anyway, just to show ( and to check ) I'm in the right thread, here's a picture of my problem:
I just installed the thing not too long ago and then it tells me Access Denied in a Windows Error Message. For the main part, I have no other accounts on my computer so I'm the computer administrator by default. This is all the information I know about my computer:
Processor: Intel Celeron
OS: Windows Xp
Brand: Compaq Presario
RAM: 512 ( 504 to be technical )
HD: I have 2. One is partioned by default with one as the OS and the other as a recovery partion. Combined, it's around 74GB or so. The other one is...I forgot the name but it's 80GB.
Name of Game: Sim City 4 Deluxe Edition
